That wouldn't really help people without IF and the complaints wouldn't stop
The point is, people without IF are either archers themselves, dedicated cav players or shielders of any kind, and for those it wont make much difference, but for pure infantry who spend a point or five or seven in IF it might make hell of a difference.
At least what i think, but hey, then we could get heavy IF unkillable archers aswell.
Edit: Also, i can see how the change planned for next patch with changed dmg to body and headshots will lead to: NERF ACCURACY, now i get HSed all the freaking time.
